I look around on craigslist once in awhile just to see whats on there and came across a guy selling a supercharger and intercooler off of a 3.8L 94 t-bird for only $200. Considering the mustang 3.8L and the 4.2L are very similar I was wondering if there might be any possible way I could get this supercharger to work with my 99 f150 w/ 4.2. Thanks.

 

Lots of threads on this already, search the V-6 and the superchargers forums.

 

my buddy is going to put a 3.8L supercharger on his 5.0L bronco soon....it'll take a few mods but it'll work.
